Prevent and Mitigate Battery Events with AES SAFE

SAFE System

SAFE System — When Safety Isn’t Optional
AES’s SAFE System is a purpose-built suite of safety features engineered specifically for battery testing. Unlike general-purpose environmental chambers, the SAFE System is intentionally designed to prevent hazardous battery events before they occur—because when you're testing energy-dense cells, safety isn’t optional, it’s essential.

Built into our chambers from the ground up, the SAFE System incorporates advanced hazard prevention features like temperature-limited sheath heaters to keep heating elements below auto-ignition thresholds, and integrated safety thermocouples that can be placed directly on the battery cell to monitor abnormal temperature rises in real-time. These sensors also allow users to set customizable high-temperature limits for proactive shutoff and alerting.

Additional user-configurable controls include maximum test setpoint limits to avoid test profile errors, and rapid temperature rise detection for early intervention. In the event of a thermal incident, robust mitigation features activate—including atmospheric inertization for fire suppression, a low-flow pressure relief vent to safely exhaust cell gases, and a graphite burst disk for emergency pressure relief.

For more extreme testing conditions, an abuse testing configuration is available, expanding temperature capabilities while maintaining the SAFE System’s core commitment to safety.
